I have a blog entry that describes the concept of what this is trying to do (not everything is implemented), and another post on the desklet dev list with more details. The short description is that it’s sort of a window manager for desklets (desklets are the same concept as gadgets or widgets) with a magnet metaphor.

There’s a lot of changes being committed to AB5K now, so this desklet won’t work for long. Give it a try if you get a chance.
